| Abstract: | Three complexes of picolinamide (pyridine-2-carboxamide, pia) and metal thiocyanates, M(SCN)2, (M = Zn, Cd, Hg), namely two polymorphs of bis(picolinamide-N,O)-bis-(thiocyanato-N)zinc(II) (1a and 1b), catena-[bis(μ-thiocyanato-S,N)-picolinamide-N,O-cadmium(II)] (2) and bis[(μ2-thiocyanato-S-thiocyanato-S-picolinamide-N,O)mercury(II)] (3) have been prepared and characterized by spectroscopic, thermal and X-ray crystallographic methods. The IR and thermal data correlate with the structures of the complexes in the solid state. The vibration bands of diagnostic value are compared to the values of the free ligands. |
